The Edit Distance Function of Some Graphs
The edit distance function of a hereditary property đŁ is the asymptotically largest edit distance between a graph of density p â [0, 1] and đŁ. Denote by Pn and Cn the path graph of order n and the cycle graph of order n, respectively. Let C2n*C_{2n}^* be

d-Path Laplacians and Quantum Transport on Graphs
We generalize the Schrödinger equation on graphs to include long-range interactions (LRI) by means of the Mellin-transformed d-path Laplacian operators.

Note On The Game Colouring Number Of Powers Of Graphs
We generalize the methods of Esperet and Zhu [6] providing an upper bound for the game colouring number of squares of graphs to obtain upper bounds for the game colouring number of m-th powers of graphs, m â„ 3, which rely on the maximum degree and the ...

(Generalized) Incidence and Laplacian-Like Energies
In this study, for graph Î with r connected components (also for connected nonbipartite and connected bipartite graphs) and a real number Δâ 0,1, we found generalized and improved bounds for the sum of Δ-th powers of Laplacian and signless Laplacian ...

Kernelizing MSO Properties of Trees of Fixed Height, and Some Consequences [PDF]
Fix an integer h>=1. In the universe of coloured trees of height at most h, we prove that for any graph decision problem defined by an MSO formula with r quantifiers, there exists a set of kernels, each of size bounded by an elementary function of r and ...

Powers of Hamilton cycles in pseudorandom graphs [PDF]
We study the appearance of powers of Hamilton cycles in pseudorandom graphs, using the following comparatively weak pseudorandomness notion. A graph $G$ is $(\varepsilon,p,k,\ell)$-pseudorandom if for all disjoint $X$ and $Y\subset V(G)$ with $|X|\ge ...

Chained graphs and some applications
This paper introduces the notions of chained and semi-chained graphs. The chain of a graph, when existent, refines the notion of bipartivity and conveys important structural information. Also the notion of a center vertex $$v_c$$ v c is introduced. It is

Accessibility percolation on Cartesian power graphs
AbstractA fitness landscape is a mapping from a space of discrete genotypes to the real numbers. A path in a fitness landscape is a sequence of genotypes connected by single mutational steps. Such a path is said to be accessible if the fitness values of the genotypes encountered along the path increase monotonically. We study accessible paths on random

On the multipacking number of grid graphs [PDF]
In 2001, Erwin introduced broadcast domination in graphs. It is a variant of classical domination where selected vertices may have different domination powers. The minimum cost of a dominating broadcast in a graph $G$ is denoted $\gamma_b(G)$.
